Less than 5% of patients with metastatic cervical carcinoma will not have a detectable primary site despite a proper work-up. Recent aids for these diagnostic problems include fine needle aspiration and immunohistochemical panels to differentiate undifferentiated carcinoma from melanoma and/or lymphoma. CT scanning can suggest areas in the upper aerodigestive tract for biopsy and can be helpful in suggesting the pathology of the enlarged lymph nodes. EBV titers are often elevated when a nasopharyngeal carcinoma is small. Aggressive treatment of the occult primary patient with metastatic melanoma, thyroid cancer, and metastatic cancer presumed to arise from the skin of the head and neck or the mucous membranes of the upper aerodigestive tract is indicated as long-term survival is often achieved.

Objective: To develop a nomogram prediction model for occult lymph node metastasis (LNM) in patients with cT1-2N0 buccal squamous cell carcinoma (BSCC), then to compare its predictive efficacy against depth of invasion (DOI).
Methods: Clinical data were retrieved for patients undergoing primary tumor resection and neck dissection from June 2020 to August 2024. Based on the risk factors screened by Lasso regression, we established four candidate models: logistic regression, random forest, support vector machine, and XGboost.

Department of Plastic Surgery, First Affiliated Hospital of Kunming Medical University, Kunming City, Yunnan Province, China.
Objectives: There is no consensus on elective lymphatic dissection of the parotid and neck for nonmelanoma skin cancer (NMSC) due to challenges in detecting occult spread to these regions. This study aimed to summarize clinical data and evaluate correlations between risk factors, nodular metastasis, and the need for elective parotidectomy in patients with cutaneous squamous cell carcinoma (CSCC), Merkel cell carcinoma (MCC), and apocrine carcinoma (AC) of the head and neck, all with clear surgical margins and negative imaging results for regional metastases.
Study Design: We retrospectively reviewed 166 patients with CSCC, one with MCC, and one with AC of the head and neck, all treated surgically between September 2006 and July 2022.

Objectives: To assess the therapeutic effects and safety of Tongxie Yaofang (TXYF) granules vs placebo as an alternative treatment for diarrhoea-predominant irritable bowel syndrome (IBS-D). We hypothesised that TXYF would improve clinical responses among patients with IBS-D.
Design: A randomised, double-blind, placebo-controlled, phase II, superiority trial.

Objective: The goal of this study was to better understand the epidemiology, clinical characteristics, and treatment outcomes of head and neck sarcomas using real-world data from Japan.
Methods: Using the Japanese Head and Neck Cancer Registry, we identified 438 patients who were pathologically diagnosed with head and neck sarcoma between 2011 and 2020. We compared epidemiological, clinical, and prognostic data for the different histological types of sarcoma.

Background: Occult papillary thyroid carcinoma (PTC) refers to the PTC accidentally found due to its occult lesions. Classic, as the most common subtype of PTC, is usually considered to have a low degree of malignancy and a favorable prognosis. Currently, the American Thyroid Association Management Guidelines adopted active surveillance (AS) as an alternative to immediate surgery in some low-risk PTC patients with less than 1 cm in diameter.
